MACHINE FOR TRIMMING THE ENDS OF PAPER VESSELS.

SPECIFICATION forming part of Letters Patent No. 335,078, dated January26, 1886.

Application filed July 21, 1884.

To all whom it may concern:

Be it known that we, HENRY W. LEONARD and JOHN STEvENs, residing,respectively, at Syracuse, in the county of Onondaga, in the State ofNew York, and Port Byron, in the county of Cayuga and State of New York,have invented new and useful Improvements in Machines for Trimming theEnds of Paper Vessels, of which the following is a specification.

This invention relates to an improvement in machines for trimming theends of paper pails and similar hollow vessels made of paper-pulp orsimilar material, and has for its object to produce a machine by whichthe operation of trimming the paper pail or vessel can be rapidly anduniformly effected.

Our invention consists, to that end, of the improvements which will behereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal section of ourimproved cuttingmachine. Fig. 2 is a top plan view thereof, and Fig. 3an end elevation of the same.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame of the machine.

B represents the base-plate, supported on the frame A and provided withtwo standards, I) b, having bearings 12' b at their upper ends, in whichis journaled a horizontal shaft, 0.

G rep resents a driving-pulley mounted on the shaft 0, between thebearings b b.

D represents a mandrel secured to the projecting end of the shaft 0, andadapted to receive and hold the paper pail or other vessel which is tobe cut.

at represents a number of annular bands, rings, or hoops of soft metal,preferably Babbitt metal, applied to the periphery of the mandrel D atthe points where the cutters operate against the same.

E E represent-two circular-cutters mounted, respectively, on arbors e e,which are secured to the upper ends of standards F F. The latter restwith their lower ends on a guide-bar, G, which is arranged parallel withthe shaft 0, on one side of the mandrel D. The guide-bar supportingSerial No. 138,383. (No model.)

G is provided with a longitudinal dovetail groove, 9, and the lower endsof the standards F F are provided with dovetail tenonsf,which slide inthe grooveg, so that the standards F F and cutters can be adjustedparallel with the shaft 0, in order to bring the cutters in contact withtheinandrel D at varying distances from the end thereof. The standards]?Fare secured in the dovetail groove of the guide-bar G by setscrews f orother suitable means.

H represents a dovetail guide arranged at right angles to the guide-barG and below the same, and secured to the upper side of thesupporting-frame A.

h represents dovetail lugs formed on the under side of the guide-bar Gand engaging with the dovetail guide H, so that the guidebar G,standards F F, and cutters secured thereto can be adjusted toward orfrom the mandrel D by moving the guide-bar G in one or the otherdirection on the dovetail H.

I represents a feed-screw journaled in bearings i on the dovetail guideH, and arranged centrally on the same at right angles to the guide-barG.

J represents a screw-threaded lug formed on the guide-bar G and engagingwith the feedscrew I, so that by turning the latter the guideba-r G ismoved on the dovetail guide H in one .or the other direction, as may bedesired.

The feed-screw I is provided with a handcrank, K, or hand-wheel,forturning it.

When the machine is used for cutting or trimming the ends of paperpails, the mandrel D is made tapering, as shown, to correspond with thetaper of the pails to be cut, and the hoops d are arranged in the properplaces on the mandrel to receive the thrust of the cutters E E incutting or trimming both ends of the pail. The cutter E is made largerin diameter than the cutter E, so that both cutters are broughtsimultaneously in contact with the pail on the mandrel.

The pail to be cut is placed on the mandrel, and the cutters are movedagainst the mandrel by the feed-screw I. The mandrel is rotated by meansof a belt running around the pulley G, and the rotary movement of thepail is imparted to the cutters as soon as they are brought in contactwith the paper pail on the mandrel. The cutters readily penetrate thepail, and two circular cuts extending around the pail are produced inthis manner expeditiously. As the cutters are secured to the guide-barG, the pails are all cut to the same length.

If it is desired to cut paper pails, or vessels in two in order toproduce shallow vessels for instance, cuspidors-one of the cutters isarranged centrally on the guide-bar G, so as to out against the centralring, (2. The rings d d being made of soft metal receive the thrust ofthe cutters without injury to the latter, and the rapid movement of thecutters tends to keep their cutting-edges sharp.

We claim as our invention 1. The combination, Witha revolving taperingmandrel, of two circular cutters of different diameters adapted to bearsimultaneously 20 against the mandrel, substantially as set forth.

2. The combination, with a revolving mandrel, D, of a circular cutterattached to a standard, F, a guide-bar, G, arranged lengthwise of themandrel and supporting the stand- .2 5 ard F, a guide-bar, H, arrangedtransversely to the guide-bar G and supporting the latter, and afeedscrew, I, substantially as set forth.

Witness our hands this 7th day of May, 1884.
